New Yorker's Remnick to write Obama biography

Knopf announced Monday that it will publish a biography of Barack Obama by New Yorker editor David Remnick that charts the president's evolution from a confused, biracial young man to an icon of hope.

"The Bridge: The Life and Rise of Barack Obama" will be released April 6.

Remnick is the author of "Lenin's Tomb," the Pulitzer Prize-winning tale of the collapse of the Soviet Union, and of "King of the World," the story of Muhammad Ali during the civil-rights movement.

The Obama biography relies on hundreds of interviews with a range of the president's associates, including family, friends and rivals. Remnick talked to controversial figures such as the Reverend Jeremiah Wright, Bobby Rush and Bill Ayers. President Obama also sat down for interviews with the author.
